   Collapse AllGets or sets the watermark mode activity.
|
| VARIANT_BOOL SwitchedToWatermark { get; set; } |
Value
VARIANT_TRUE if the watermark mode is switched on, VARIANT_FALSE otherwise.
Remarks
If SwitchedToWaterMark is TRUE, all PDFPAGE_* commands are applied to the watermark, created by the CreateWaterMark method. The index of the current watermark can be obtained by using CurrentWaterMarkIndex. When you use Watermark functions, you must set the watermark to the page BEFORE all other output functions.
Analogue in new interface: IPDFDocument4::SwitchToWatermark, IPDFDocument4::SwitchToCurrentPage.
